Ansible-Execute a last mandatory role in the playbook even though any previous roles in the execution flow fails - ansible

Question

I have ansible playbook something like this
---
- hosts: localhost
connection: local
tasks:
- set_fact:
build_date_time: "{{ ansible_date_time }}"
- hosts: localhost
connection: local
gather_facts: false
vars:
role: Appvariables
base_image_tag: Base
roles:
- role: begin-building-ami
- hosts: just_created
remote_user: "{{ default_user }}"
vars:
role: AppName
roles:
- { role: role1, become: yes }
- role: role2
- { role: role3, become: yes }
- { role: role4, become: yes }
- { role: role5, become: yes }
- hosts: localhost
connection: local
gather_facts: false
vars:
role: Appname
ansible_date_time: "{{ build_date_time }}"
roles:
- finish-building-ami
Here in this case we have a situation to execute the finish-building-ami role where we terminate the instance after baking the ami. If any reason any of the previous role1-role5 fails in the flow fails It stops the playbook and we have the failed instance which we needed to terminate automatically.Right now we are going and terminating it manually if it fails.
So needed to run finish-building-ami(mandatory role where we stop the instance and take ami and terminate the instance at last ) if even any of the role1-role5 fails in the above mentioned playbook.

Answer 1

You can rewrite your existing play to use import_role or include_role tasks instead of the roles section. This allows you to use blocks:
---
- hosts: localhost
gather_facts: false
tasks:
- block:
- import_role:
name: role1
- import_role:
name: role2
become: true
- import_role:
name: role3
rescue:
- set_fact:
role_failed: true
- hosts: localhost
gather_facts: false
tasks:
- debug:
msg: This task runs after our roles.
